That will remove the code that checks for updates and shows the window.

Heads up, this method will not work. It creates two compiler errors:

Assets/I2/Localization/Scripts/Editor/Tools_NGUI_to_I2.cs(54,4): error CS0103: The name `I2AboutWindow' does not exist in the current context
Assets/I2/Localization/Scripts/Editor/UpgradeManager.cs(14,7): error CS0234: The type or namespace name `I2AboutWindow' does not exist in the namespace `I2'. Are you missing an assembly reference?

The best way to disable the manager:
Update to the latest version (2.6.10b3) from the AssetStore, The popup will never show again, unless you manually select it from the menu to see if there is an update.
Now, instead of showing the popup whenever there is a new version, it will show it as an Info icon at the bottom of the inspector, small enough to not be disturbing, but there so that you know there is a new version with improvements and new features! And as always, if you open the AboutWindow and deselect the notify when a new versions is ready, it wont even show the icon.

If you can't update:
Open the I2AboutWindow.cs file and comment the content of the function I2AboutWindow.DoShowScreen()

Hope that helps,
